Just relax and let Epic take care of it - they are aware of things such as Nanite Foliage and are working hard on making it more performant. Unclench - it will affect your health.
Constantly insulting them and demanding they do things your way is extremely counter productive and just makes you look like a child.
Meanwhile, I’ve been enjoying watching real game devs do some very cool things with UE5, Lumen and Nanite.
